최소 절삭깊이와 절삭조건의 관계에 관한 연구

조성산,유수영 弘益大學校 科學技術硏究所 2000 科學技術硏究論文集 Vol.11 No.-

Thermo-elasto-plastic behavior of half-space due to a sliding rounded cutting edge tool is analysed using finite element technique in order to investigate the relation between the minimum cutting depth and the cutting conditions. Variations of the horizontal force for tool sliding, and the maximum surface temperature and surface layer deformation pattern of the half-space at several indentation depths are examined for various sliding speed and tool/half-space friction coefficient. It is found that there exist a critical indentation depth at which the tool horizontal force and the maximum surface temperature increase rapidly and continuously without any bound and thus sliding instability occurs. The critical indentation depth is affirmatively believed to be the minimum cutting depth since the rapid increase is associated with the material pile-up occurring in front of the moving tool. In addition, the minimum cutting depth decreases with the increase in the cutting speed and tool/work friction coefficient.

정신보건법에 의한 계속입원치료 심사청구는 해마다 증가하고 있다. 이에 계속입원치료 심사의 청구서에 기재되어 있는 항목들을 바탕으로 일 지역 정신보건심판위원회의 계속입원치료 불승인 현황과 그 불승인에 영향을 주는 요인에 대해 조사하였다. 2002년 1월부터 2006년 12월 까지 5년간 정선보건심판위원회에 요청된 계속입원치료 심사청구는 총 14,782 건이었다. 이 중 불승인은 1,832건으로 약 12.4%의 불승인율을 보였다. 각 요인별 불승인율을 보면, 시설은 정신병원 10.6%, 정신요양원 14.6%이었고, 의료보장 형태는 의료보험 10.5%, 의료보호 12.9%이었고 모두 유의하게 차이가 있었다. 진단에 따른 불승인율은 알코올 중독 27.9%, 기타 17.1%, 정신지체 16.4%, 기분장애 12.5%, 정신분열병 11.5%, 기질성 정신장애 8.6% 순이었으며 유의한 차이가 있었다. 계속입원치료 심사청구 횟수와 진단에 따른 불승인율을 보면 기분장애, 정신지체, 기타 환자들은 3회-6회 사이에서 불승인율이 높았다. 심사청구 횟수와 시설을 보면, 정신병원은 4회 이상에서 정신요양원은 6회 이상에서 불승인율이 높았다. 계속입원치료 심사에 가장 영향을 주는 요인은 시설, 심사청구 횟수, 진단이었으며 주로 정신병원 입원, 알코올중독, 의료보험, 자해 및 타해의 위험성이 낮고 지남력이 좋은 환자들에서 불승인이 되는 경우가 많았다. The number of applications for judgment of continuing hospitalization by the Mental Health Act is increasing every year. Thus, the present study surveyed the current state of continuing hospitalization disapproval by the Mental Health Judgment Board of an area, and factors affecting the disapproval based on items recorded in the application for the judgment of continuing hospitalization. During the 5 years' period from January 2002 to December 2006, there were a total of 14,782 applications for judgment of continuing hospitalization to the Mental Health Judgment Board. Among them, 1,832were disapproved, showing a disapproval rate of around 12.4%. As to disapproval rate related to each factor, according to facility, the disapproval rate was 10.6% for patients at mental hospitals and 14.6% for those at nursing homes for mental patients. According to medical security type, it was 10.5% for medical insurance patients and 12.9% for medical aid patients. These differences were all statistically significant. According to diagnosis, the disapproval rate was 27.9% for alcoholism, 17.1% for others, 16.4% for mental retardation, 12.5% for mood disorder, 11.5% for schizophrenia, and 8.6% for organic mental disorder, and the differences were statistically significant. According to the number of applications for judgment of continuing hospitalization and diagnosis, the disapproval rate was higher when the number of applications was 3~6 among patients with mood disorder, mental retardation, or others. According to the number of applications for review and facility, the disapproval rate was higher when number of applications was 4 or more among mental hospital patients, and when it was 6 or more among nursing home patients. The factors most influential on the judgment of continuing hospitalization were facility, the number of applications for review, and diagnosis, and the disapproval rate was high among mental hospital patients, alcoholics, those with medical insurance, and those with low risk of self-injury and injury by others and good orientation.

원호 절삭날 공구에 의한 2차원 절삭에서 칩 분리깊이에 관한 해석적 연구

유수영,조성산 弘益大學校 科學技術硏究所 1999 科學技術硏究論文集 Vol.10 No.1

Finite element orthogonal machining model based on Lagrangian formulation requires informations for chip separation depth in order to consider cutting edge roundness effects. This study analytically determines the chip separation depth using the minimum energy principle that chip separation occurs at the depth where cutting energy is minimum. Finite element analysis is employed to estimate chip formation and plowing forces separately with an assumption that primary cutting force can be decomposed into chip formation and plowing forces. Primary cutting force is obtained by superposing the chip formation and plowing forces at various separation depth. It is demonstrated that there exist a depth at which cutting energy is minimum. A finite element simulation of orthogonal machining with a round cutting edge tool is conducted using the chip separation depth predicted in the present study.

곽주석,장훈상,장석우,이수종,유용욱,민경산 大韓齒科保存學會 2005 Restorative Dentistry & Endodontics Vol.30 No.4

세균의 용혈활성은 세균이 숙주 내에서 생존하기 위해 필요한 철을 획득하기위한 특성이며 기능면에서 볼 때 숙주에 대한 중요한 독력인자로 간주될 수 있다. 본 연구에서는 괴사치수 및 치근단 치주염으로 진단된 환자의 근관에서 분리한 Prevotella nigrescens의 용혈활성을 다양한 조건 하에서 측정하여 그 특성을 규명하는 것을 목적으로 한다. 1. 임상에서 분리한 P. nigrescers와 표준균주인 P. nigrescers ATCC 33563에서 모두 용혈활성이 나타났다. 2. 사람, 면양 및 말 세 가지 종에 대해 용혈활성을 비교한 결과 사람의 적혈구에서 가장 강한 용혈활성을 나타내었다. 3. 용혈소 억제제인 NaN₃와 dithiothreitol (DTT)는 농도의존적으로 P.nigrescers의 용혈활성을 감소시켰다 (p<0.05). 4. P. nigrescers가 최대 용혈활성을 나타내는 최적의 pH는 4이었으며, 50℃이하의 온도에서는 용혈활성을 보였으나 95℃에서 급격히 감소하였다. 5.배양조건에 따른 P. nigrescens의 용혈활성을비교한 결과 10% CO₂배양기에 배양한 경우혐기성 조건에서 배양한 것보다 더 높은 용혈활성을 보였다. Hemolytic property is a specific feature of bacteria to obtain iron which is essential for its survival in host tissues. Therefore, it is thought to be one of several factors of virulence. The purpose of this study was to investigate the hemolytic properties of Prevotella nigrescens isolated from the teeth diagnosed as pulp necrosis and apical periodontitis under the presence of hemolysin inhibitors such as NaN3 and dithiothreitol, heat, various pH and cultural conditions. The results were as follows; 1. Clinically isolated P. nigrescens strains and standard P. nigrscens ATCC 33563 showed hemolytic activity. 2. P. nigrescens showed higher hemolytic activity against human erythrocytes than sheep or horse erythrocytes. 3. NaN₃ and dithiothreitol (DTT) reduced the hemolytic activity of P. nigrescens in a dose dependent manner (p<0.05). 4. Optimal pH for the maximum hemolytic activity of P. nigrescens was 4.0 and the hemolysin was stable under the 50℃, but the hemolytic activity was significantly decreased at 95℃. 5. P. nigrescens cultured in 10% CO₂ condition showed higher hemolytic activity than the bacteria cultured in the anaerobic condition.[J Kor Acad Cons Dent 30(4):335-343,2005]

Osteoblastic cells biomineralized on bioactive glass and glass-ceramics of the SiO2.Na2O.CaO.K2O.MgO.P2O5 system modified with Al2O3 and B2O3

Irene Barrios de Arenas,Karem Noris-Suárez,Maritza Vasquez,Yotselys López,Thalia San Antonio 한양대학교 세라믹연구소 2010 Journal of Ceramic Processing Research Vol.11 No.2

A treatment study evaluates glass and glass-ceramics of the Na2O·CaO·K2O·MgO·SiO2·P2O5 system, modified with B2O3, Al2O3or B2O3/Al2O3 up to 0.66. Both, bioactivity using simulated body fluid (SBF) immersion and mineral nodule formation using calvaria derived osteoblasts, were tested. The surface structure changes were examined by SEM-EDX line scan X-ray microanalysis and calcium deposition by the alizarin-red test. It was found that all compositions of glasses as well as glassceramics reacted with the SBF, allowing the development of a SiO2 rich layer. In some cases the presence of a rich calcium and phosphorous layer was observed, that according to other studies, corresponds to the apatite layer identified in previous studies. This result suggests a bioactivity behavior, with the exception of the glass containing B2O3/Al2O3 = 0.66 and the glassceramic of the same composition with a 2nd heat treatment. The composition containing B2O3/Al2O3 = 0.66 showed the best biocompatibility with hydroxyapatite nodule formation on its surface, especially on the glass-ceramics.

김혜영,김진호,김수잔 한국체육대학교 학생생활연구소 1997 學生生活硏究 Vol.- No.3

The purpose of this study was to identify the needs and wants of the Korean National University of physical Education students with respect to the university's facilities and gazette. In particular the study attempted to determine whether there are significant differences among the needs and wants of three groups of students -athletes, industry students, and regular students. A questionnaire consisting of questions about the university's bulletin board, library, swimming pool, computer room, convenience store, rest areas, and gazette was distributed in June 1996. Students from all grades and departments except the dance department, participated in the study. The data was analyzed by employing the Chi-square test (alpha = 0.05) and by using the SPSS-Window statistical package. Variables showing a statistical difference were further analyzed by examining the cross-tabulations of the three groups and their specific responses. As a result, the following conclusions were made: (1) There is a lack of bulletin boards, and the location needing a bulletin board the most is the front gate; (2) Students generally use the library to write a report for class, but there is a lack of books and journals in the library; (3) The swimming pool is not utilized well during non-class hours because its usage is limited to certain student groups and hours; (4) Athletes consider the hours, the regular students consider the lack of computers, and the industry students consider the processing speed of the computers as the most inconvenient factor in their utilization of the computer room; (5) Many students desire to purchase products which contain the university's logo; (6) There is a lack of rest areas where students can spend their free time resulting from a cancelled class; (7) Regular students tend to be more interested in university and circle news, while athletes tend to be more interested in sport news. Nevertheless, all students are interested in reading about how their alumni chose their career and about other universities' news.
